SCHAR_MIN常数，C ++中的示例

C ++ SCHAR_MIN宏常量 (C++ SCHAR_MIN macro constant)

SCHAR_MIN constant is a macro constant which is defied in climits header, it is used to get the minimum value of a signed char object, it returns the minimum value that a signed char object can store, which is -128.

SCHAR_MIN常量是在climits标头中定义的宏常量，用于获取签名char对象的最小值，它返回签名char对象可以存储的最小值-128 。

Note:

注意：

The actual value depends on the compiler architecture or library implementation.
实际值取决于编译器体系结构或库实现。
We can also use <limits.h> header file instead of <climits> header as SCHAR_MIN constant is defined in both of the libraries.
我们还可以使用<limits.h>头文件而不是<climits>头文件，因为在两个库中都定义了SCHAR_MIN常量 。

Syntax of SCHAR_MIN constant:

SCHAR_MIN常量的语法：

    SCHAR_MIN

Example:

例：

    Constant call:
cout << SCHAR_MIN;
Output:
-128

C ++代码演示带有climits标头的SCHAR_MIN常量示例 (C++ code to demonstrate example of SCHAR_MIN constant with climits header)

// C++ code to demonstrate example of 
// SCHAR_MIN constant with climits header
#include<iostream>
#include<climits>
using namespace std;
int main()
{
//prinitng the value of SCHAR_MIN
cout<<"SCHAR_MIN: "<<SCHAR_MIN<<endl;
return 0;
}

Output

输出量

SCHAR_MIN: -128
